IIRC Spector had a lot to do with getting Pink Floyd over here for their first concert tour.
Carroll Shelby ran that Daytona coupe as a 24 hour land speed record car and afterwards he thought of it as just an old race car, so he tried like hell to sell it. No one wanted it for the same reason, it was just an old race car. It seems that when Spector was interested in it, he had Shelby bring it to his house, made him wait in the driveway for hours while he did the whole deal with a butler? as a go between. Shelby later said the sale to Spector was one of the weirdest experiences he'd ever had.
EDIT: Seems that Shelby sold the car to a guy who made model car kits, he's the guy who sold it to Spector and had the really weird experience.
